1 Claim.

The object of my invention is to provide protecting covers for books,ledgers and similar articles.

The fact that the covers are wholly or partly made of rubber, or acomposition of rubber, give the books, ledgers, note-books and similarar ticles provided with these covers many advantages, the chief of whichare the following:

(a) When the cover consists of a single sheet of rubber or of acomposition of rubber, the shaping of the back and the fixation of theboards to said back, which operations are necessary in ordinary bookbinding, are completely done away with, involving a considerablesimplification in manufacture, and consequently a substantial reductionof the cost;

(17) The covers made of rubber, or a composition of rubber are washableand therefore very hygienic. This advantage is particularly importantconcerning books or note-books for children.

(0) These covers can be decorated in any suitable way, in hollow, inrelief, by the composition of the matter itself; these decorations canbe obtained for instance by moulding, gauffering,

printing, gilding, painting, etc.

t is known for instance that white or very light coloured bindings arerarely used, although they are very convenient in some cases, becausethese bindings are quickly soiled. The improvements according to myinvention make it possible to utilize bindings of this colour owing tothe facility with which rubber covers can be cleaned.

Preferred embodiments of my invention will be hereinafter described withreference to the accompanying drawing given merely by way of example,and in which:

Fig. 1 is a plan view of the inner side of a cover according to thepresent invention;

Fig. 2 is a corresponding profile view;

Fig. 3 is also a profile view showing the leaves of a book assembled andready to be fixed to the cover;

Fig. 4 is a partial cross sectional view on an enlarged scale of thecovers shown in Fig. 2.

In all the covers shown in the drawing, I and I designate the boards ofthe cover, and 2 its back. As shown by Figs. 1 and 2 these three partsare made in a single piece of a composition of matter consisting chieflyof rubber. Each board is divided between the edge of the back and a line:r-.r into two portions, an outer one 3 which is directly connected toback 2 and another one 4 which forms an inner flap.

The boards I and l are sufficiently thick for being relatively stiff.The back 2 consists of a band of reduced thickness so as to be moreflexible.

The fixation of the leaves of a book as shown in profile in Fig. 3 isperformed in the following manner:

These leaves have been secured in a known manner, for instance by sewingor gluing, to a sheet T extending on either side thereof so as to formtwo small flaps V. The portion T of this sheet is fixed, by glue forinstance, to the back 2 of the cover, while the two flaps V arethemselves glued between portions 3 and flaps 4 of the two boards of thecover. Sheet T and its flaps V are preferably made of fabric; saidfabric may be rubberized and in this case it may be fixed to the coverby means of a suitable adhesive thus giving the whole a very greatstrength.

Fig. 4 is a partial cross section on an enlarged scale of the embodimentshown in Fig. 2. A lining H of a suitable material, fabric or paper forinstance, is applied on the inner face of said back and the two edges l2of said lining are applied against the inner faces of flaps l0. 5

While I have described what I deem to be practical and efiicientembodiments of my invention, it should be well understood that I do notwish to be limited thereto as there might be changes made in thearrangement, disposition and form 30 of the parts without departing fromthe principle of my invention as comprehended within the scope of theappended claim.

What I claim is:

A permanent protective cover for books, ledgers and similar articles,which comprises in combination, a single sheet of a composition ofrubber sufficiently thick for being relatively stiff, said sheet beingprovided in its intermediate part with a band of reduced thickness so asto be more flexible, which band forms the back of the cover, theportions of said sheet on either side of said band forming the boards ofthe cover, flaps integral with said boards and extending on the innerside thereof along the portions thereof adjacent to the back, said flapsbeing turned toward each other and adapted to serve to the fixation ofthe leaves of the book to the cover, and a band of cloth applied againstthe inner side of the back and the inner sides of the flaps the totalthickness of each flap and the portion of the board over which itextends being equal to the thickness of the remainder of said board.
